To improve understanding of global freshwater responses to multiple
stressors, valid, standardized and accurate data are needed. In
collecting data in the field, there are logistical, operational and financial
considerations that usually impede freshwater ecosystem measurements.
In situ measurements andmonitoring provide detailed information
pertinent to understanding key ecosystem characteristics, forming
the basis of long term monitoring records needed to assess status and
identify trends. Unfortunately, in situ approaches are limited to pointbased
representations of complex and dynamic systems. Furthermore,
in situ measurements in freshwater systems are also limited by logistics
such as access, cost and timing, which all restrict systematicity. Satellite
remote sensing can complement in situ freshwater ecosystemsampling
